Chapter 1, Introduction to Azure Functions, will walk you through the basic understanding of Azure Functions and then its serverless functionalities. In this chapter, we will learn to create, debug, and deploy the Azure Functions. Later in the chapter, we'll deal with serverless runtime functions of Microsoft's Azure Function.

Chapter 2, Deploying Azure Serverless, will help you to integrate your Azure Function with Cosmos DB, and with an Azure App Service. Later in the chapter, we'll use APIs to secure the Azure Functions and using Azure Application Insights we'll combine a complete logging and monitoring solution.

Chapter 3, Architecting Serverless Solutions, will be dealing with triggering functions with Cosmos DB and changing the functionality from an old .NET app to an Azure Function. We'll be developing a weather-dependent notification for our personal finance app. Later in the chapter, we'll analyze how to integrate old applications using serverless architecture.
